The JRX215 is a portable, fifteen-inch, two-way speaker system designed
specifically for applications in live music, music playback, and
reinforcement of speech. With the smooth, natural sounding mid-range of
the system, the JRX215 does a great job projecting live vocals, solos and
speech. The extended lows and great top-end make it at home for music
playback in DJ applications or anywhere live sound reinforcement is
needed . Features include the dual-angle, 36 mm pole-mount socket as well
as Neutrik

JBL continually engages in research related to product improvement. Some materials, production methods and design
refinements are introduced into existing products without notice as a routine expression of that philosophy. For this
reason, any current JBL product may differ in some respect from its published description, but will always equal or
exceed the original design specifications unless otherwise stated.
